'MACHINE FOR PUTTING HEAD-FILLINGS ON TRUNK-NAILS.y

Specification forming part of Letters Patent No. 48.465, dated June 27,1865.

To all whom it may concern: Be it known that I, ZACHARIAH WALSH, ofNewark, in the county of Essex and State of New Jersey, have invented anew and useful Machine for Putting Head-Fillings on Trunk and SimilarNails; and I do hereby declare that the following is a full, clear, andexact de` scription thereof, which willenable those skilled in the artto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figurel, SheetNo. 1, is a front sectional elevation of my invention, taken in the line.rx 00x, Fig. 2; Fig. 2, a view of a trunk'nail having the pasteboardand sheet-metal fillings upon it; Fig. 3, a side View of a trunk-nailcom@` plete; Fig. 4, a longitiidinal central section of the same, takenin the line xx, Fig. 3 5 Fig. 5, Sheet No. 2, a side elevation of theinvention Fig. 6, Sheet No. 3, a side view oi' the same, oppositeto thatshown in Fig. 5; Fig. 7, Sheet No. 4, a plan or top view ofthe same;Fig. 8, Sheet No. 5, a horizontal section of the same, taken in the liney y,`Fig. l; Fig. 9, a horizontal section of the same, taken in the linez z, Fig. l; Fig. l0, a vertical section of a portion of the same, takenin the line x', Fig. 8; Fig. l0, avertical section of a portion of thesame,

Y

This invention relates to a new and useful machine for putting thepieces of pasteboard which are fitted on the body A ot' the nail justbelow the head B. My invention places these parts C D on the nail, saidparts forming the principal portion of the filling of the enlarged head,the vother portion of the lling being a circular piece of pasteboard,a., (see Fig. 4,) and a sheet-metal cover, b, the pasteboard a beingover or at the outer side ofthe head B, and the metal cover b` beingover a, and pressed down and closed around under the edge of C, as shownclearly in Fig. 4..

The placing of the parts a, b on and over the parts O D may be done inthe usual or in any proper way, my invention, as previously stated,

only putting the parts C D on the nails, which it does veryexpeditiously and in a perfect manner. y V

In order to avoid confusion, I will proceed, in the first place, todescribe the mechanism pertaining to the placing ot' the sheet-metalplates G in the part Where the nails are forced through them.

E represents a fra-min g, and F a horizontal platform thereon.

Gr is a shaft, which is placed horizontally in the framing E, and hasits driving-Wheel H fitted loosely upon it and connected to i-t by aclutch, I. (See Figs. 5 and 6.)

J is a hopper, supported by an upright, K, which is secured to theplatform F, the hopper J being attached to the upright K by means of ascrew, c, which passes through a pendent lip, d, at the under side ofsaid hopper, as shown clearly in Fig. 5. By this means the hopper J maybe adjusted in a more or less inclined position, as desired.

At the discharge end of the hopper J there is a guard or flap, L, whichhas a vertical, or nearly vertical, position, and is designed to give aproper direction to the contents of the hopper J in their discharge fromit, causing the same to fall into a spout, M, which is. at the outerendof a bar, e, attached to the upright K.

The sheet-metal plates O are cut out in circular form of the properdiameter by any suitable die or dies, and they are placed into thehopper J, and in passing therefrom 'are directed into a vertical tube,N, by the guard or ap L` and spout M.

The tube N is litted in brackets f attached to the platform F, and insuch a manner that driven through them.

it may be readily adj usted to the platform and detached from it, andsaid tube is perforated with holes g, extending its whole length, (seeFig. 1,) so that the attendant of the machine may see when the tube N islled and watch the progress of the iilling of the tube. The upper endofthe tube N passes through au inclined spout, O. (See Figs. 5 and 6.)This spout O is designed to carry off any plates G which may fail topass into tube N. The plates C thus carried oil may drop into any properreceptacle prepared to receive them, and from time to time the contentsof said receptacle may be turned into hopper J. During the lling of thetube N the latter is knocked or tapped by a set-screw, h, which passesthrough the end of an arm, t, of a bent bar, P, which works on a rod, j,the knoekor tap on the tube N being produced by a spring, Q, connectedwith the bar F, the opposite movement of said bar being given by a cam,R, on the shaftG. (Shownelearlyin Figsand 6.) This filling of the tube Nwith the circular plates C is a distinct operation, and when said tubeis filled it is removed from the bracketsfand placed in another partofthe platform F. This second position of the tube is the one where theplates C are taken from it, and it is designated in the drawings by N'.Two tunes, N N', therefore, must be necessarily employed during theoperation of the machine, one being filled with plates O from the hopperJ, while the other has its plates C taken from it to be placed in acertain part, hereinafter described, to be punched and have the nails AThese tubesNN' have a hole made centrally in their' bottoms or lowerends to admit of a rod,"S, passing through. This rod passes only into orthrough the bottom of the filled tube N', and said rod S is attached t0a horizontal plate or arm, 7c, t0 which another vertical rod, T, issecured, the latter passing up through the platform F, and having abeveled or inclined surface, l, at its upper end. (See Figs. 1, 5, and6.) The function of this rod T will be hereinafter described. The plateor arm k has a cord, U, attached to it, which passes over a pulley, m,and has a weight, V, at its end. This weight and cord causes the rod Sto press the plates U in the tube N' upward, as will be fullyunderstoodby referring to Figs. l and 10,

l The tubes N N' are each provided with a spring, n, inserted inalongitudinal slot at theirupperparts. (SeeFig.10.) Thesesprings, inconnection with pressure-levers, hereinafter described, prevent the rodS from shoving the plates C out from the tubes, as will be fullyunderstood by referring to Fig. 10, in which the spring n is shownpressing against the upper plates C in tube N' The tube N' istted in theplatform F in such a manner that it may be readily adjusted in theposition shown, and also readily removed from said position. This isnecessary in order that N', when exhausted of plates G, may be removedand a filled tube,

N ,inserted in its place, N' being then adjusted in the place shownoccupied by N, in order that it may be filled from the hopper J.

The plates C are taken from the tube N' by means of atmosphericpressure, the suction orl vacuum in the lifter being produced by a pump,W, (shown in Figs. 1, 5, 6, and 7.) Any suitable form of air-pump may beused. The one represented in the drawings is composed of a cylinder, o,having an elastic or flexible diaphragimp, to serve as a piston. (Seemore particularly Fig. 9.)

The lifter (designated by X) is composed of a cylinder', q, the interiorof which is of sufficient diameter to receive a plate C. `(See Fig. 10.)This cylinder is provided with a plungerrod, r, which passes verticallyinto it and has a spiral spring, s, on its upper part above thecylinder, which spring has a tendency to keep the plunger-rod r elevatedin q, a collar, t, on r bearing against the upper end of q, as shownclearlyin Fig. 10. The cylinder q is attached to and communicates with ahorizontal tube, u, which is attached to a vertical tube, c, the latterbeing lifted in a stock, w, so as to turn freely therein. (See Fig. 10.)The air-pump W communicates with the vertical tube v by means of atube,a', which passes into the stock w and in line with a portion of e, wherea hole,

b', is made, as shown clearly in Fig. 10. The upy per end ofthe tube chas a bar, Y, attached to it, which is bent so as to have a horizontalpart, c', and an upright curved part, d'. The end of the horizontal partc' has a spiral spring, e', connected to it, which has a tendency tokeep the upright curved part d' in contact with a roller, f', at theouter end of an arm,g", which projects from a vertical reciprocatingslide, Z, the latter being fitted between suitable guides h' h', securedto the platform F. (See Figs. 1, 5, 6, and 7.)

A represents a horizontal wheel, which is fitted on avertical shaft, B',the latter passing through the platform F, and the wheel A' being abovethe latter and working over a fiXedannular rim or ledge, i', on theplatform. (See more particularly Fig. 1] This wheel A.' has a series ofholes made in it near its periphery to ders in the holes of the wheelA', as shown clearly in Fig. 10.

O11 the shaft B', underneath the platform F,

there is keyed a ratchet, C', and on the shafty B', directly below theratchet, there is placed loosely an arm, D', which has a pawl, E',attached to it, said pawl engaging with theratchet, as shown clearly inFig. 9. This arm D' is connected by link F' with a lever, G', the lowerA neath the platform F. so as to force the piston or diaphragm inward ithe arm D' acting upon the slide to rend of which is kept in contactwith a'eam, H',

on the shaft G, by a spring, 1'.. By the movement of the lever Gr',actuated by the cam H' andsprin g I', the ratchet C', and consequentlythe wheel A', areturned. i

The slide Z, previously alluded to, is operated by a connecting-rod, J',from a crank, K',

f circular plates() being forced up out of tube N' by the rod S, and,inA order to admit of a plate, C, being taken from tube N', the spring amust be relieved of the pressure of the lever L'. This is effected bymeans of an arm, n?, on a slide, M', which works between guides m' onthe platform F, and is operated by means of a bent-lever, NX, from acam, O', on shaft G, the lever being kept in contact with the cam bymeans of a spring, P'. y

The Wheel A' is prevented from casually moving` by means of twoholding-pawls, Q' R', one, Q', being thrown out from the ratchet C',when itis moved or turned by the pawl E', by the end of the arm D',which is opposite to the end where the pawl E' is attached. The other ipawl, R', is an ordinary holding-pawl, and has no positive movement.

The rod fn' of the piston or diaphragm p of the pump Wis connected to aslide, S', under- This slide isoperated by means of the arm D', whichacts against it,

i and said slide is movedin the opposite direction by a hook, T',attached to the arm D' at such a point that it will catch behind a stud,o',on slide S', in order to draw it back or outwardand relieveitselffrom said stud prior to press the piston or diaphragm inward.

The operation of the partsabove described i is as follows: The tube N,having been filled with plates C fromhopper J, is placed in the iframing, as indicated in thc drawings, and the shaft Gis rotated by anyconvenient power.` As the slide Z is forced upward by the crank K' andconnecting-rod J', the roller j" at the end of the arm g', inconsequence of bearing against the curvedupright part d' of the barY,turns the cylinder q of ,the lifter X over the top of the tube N', andat this moment the pis! tonyor diaphragm p is drawn outward bythe hookT' engaging with the slide S', and a suction is produced in cylinder q,so as to take up a plate C from N', the hole` b' in the `tube i c comingin line with the tube a' just at the time that the cylinder q is broughtin line with thc'tube N'and` in orderto admit of the top plate@ in N'beingreleased in order'that it may be sucked up intoA q, the slide `M isshoved 4by the lever4 N backward or outward, so that thetarm a? will actagainst the lever L' and be freed from the spring n, which holds the topplate C, the slide M' being moved back to its original position as soonas the top plate C leaves N' by means of the spring P'. When this topplate has been sucked up to the cylinder q, the latter is turned overthe edge ofthe wheel A', this being done by the spring e' during thedownward movement of the slide Z and rollerf', and when the cylinder isover a die j' in the wheel A a lateral projection, p', on arm g forcesdown the plunger-rod 1' in the cylinder q, and discharges the plate Ctherefrom into the die underneath it. When the cylinder q is moved offfrom the tube N', the hole b' in the tube'fv is out off from thc tube a'of the pump W, and the piston or diaphragm p is moved back by the arm Dacting against slide S', the air in the cylinder o of the pump beingforced out through a valve, o2. Thus by this means the diesj' of thewheel A' are supplied with the plates C from the tube N", the wheel A'being moved by the pawl E' and ratchet C' the distance of one tooth ofthe latter each time the cylinder q is moved from over the wheel A', sothat an empty die j' is presented to the cylinder q each time the latteris brought over the wheel A'. a stop mechanism connected with thisplacing ofthe plates G in the diesj' of the wheelA',l

It is constructed and arc'on'nected to it which extends upward somedistance above the platform F and has a rod. V"," attached to its upperend.` To the rod V there is connected a spiral spring, W', which has atendency to keep the clutch l free from the wheel H, so that the latterwill turn loosely on shaft G. In order to keep the clutch I engaged withthe wheel H, a catch, X', is employed, (shown clearly in Fig. 7,) andhaving a spiral spring, q', connected with it, which spring has atendency to keep the catch engaged with a pin, r', on thc'rod 'V' andcause theclutch I to keep locked with wheel H. This cat ch X' has afriction-roller, s', ou` its outer i end, and when the last plate G isforced out from the tube N' the upper b'eveled end, l, of the rodT willcome between the roller s' on the catch X' and a plate, t', attached. toa fixture onthe framing, and will actuate the. catch X' so as todisengage it from pin r', and thereby liberate the rod V', so that thespring W' will throw the catch Ifree from wheel H, and cause the'machineto stop.

I jwill now proceed to describe the operation of placing the pasteboardD in the dies j' of thedwheel A'. y

`Y' is a tube, which is placed in a fixed state `above the platform Fand is perforated with holes, likethe tubes N Ni'.

, ZL is ahopper, provided with a guard or flap, .:A", and B" is a spoutbelow theguard or flap, the guard or flap` and spout conveying thepasteboards into tubeY' in precisely the same way as the plates() areconveyed into the tube N. The tube `Y' is `knocked or tapped by a set-Thereis i a die,j, which is in line with it.

screw, w', which passes through an arm,a,at the upper end of the bar P,both tubes N Y being acted upon hy the same bar. The tube Y is open atits lower end, and is directly over a plate, b, between which and thelower end of the -tube a plate, C, attached to the slide M works. (Seemore particularly Fig. 10x.) The outer end ofthe plate C has asemicircular recess, c, .made in it, and each time the slide i is forcedinward the plate C shoves a pasteboard D from underneath tube Y intoThese pasteboardsD are each placed on a plate C previousl)1 forced intothe dies by the means already described.

I would remark that the upper end of the tube Y passes through the upperend of an inclined spout, D, which carries oft' those pasteboards whichdo not chance to drop into said tube.

This manner of depositing the pasteboards D into the dies j is quitesimple compared with the means employed for depositing the plates C inthe dies, but the latter,.in consequence of being quite thin, cannotwith any degree of certainty be actuated or shoved from underneath theirtube by a slidingplate. rI he pasteboards D, being comparatively thick,may be acted upon by a slide in a perfect manner.

To insure the perfect operation of the machine, itis essential that theplates G and paste# boards D be inserted in each diej', and in order toprevent a failure in this respect a stop mechanism is employed for each,as follows:

E is a vertical rod, which passes loosely through a hub, d, on the armgef slide Z, said rod also passing loosely through a plate, e, whichworks on a pivot, f, and has an upright arm, g, attached to it, theupper end of which is connected by a link, h, with the catch X. (Seemore particularly Figs. l and 7.) On the rod E, between the hub d andthe plate e", there is placed a collar, t, which may be secured at anydesired point by a set-screw, and on the rod, below the arm g', there isplaced a similar collar, j, between which and the arm g there is aspiral spring, 7c, said spring heing on the rod E and ,having a tendencyt0 keep the collar i down on the hub d, as shown in Figs. 1, 5, and b. Acollar, Z, is also placed on the rod E, near its upper end. The rod E"is directly in line with the center ot' the path of the movement ofthedies j', and each time the slide Z descends the rod E passes into a die,j', provided with a plate C, and the lower end ofthe rod E comes incontact with the plate C before the slide Z reaches the termination ofits downward movement;'but the arm g, acting upon the spring la andcom-V pressing it when the rod E is stopped by coming in contact withthevplate C in the die j and the collar l, on the upper end of rod E,will be prevented from coming in contact with the plate c". lf, however,a plate (l should fail to be deposited in a die, j', the rod E would be,of course, pressed down farther, and the -the hopper H, with two plates,q q.

. collar l on its upper end will come in contact with the plate e" andpress it down, and cause the arm g of said plate and the link h toactuate the catch X and liberate the rod V', so that the spring` W willthrow the clutch I in connection with the wheel H.

The stop mechanism connected with the pasteboard-adjustin g device isarranged precisely similar.

F is a-rod which passes loosely through the arm g', and has threecollars upon it, arranged or disposed in precisely the lsame way as thecollars Wj Z on-the rod E. A spiral spring, p, is also placed on rod F,in the same position as the spring k on rod E. In case a pasteboard Dshould fail to be'deposited in a die j', the plate e will be actuated bytheA collar o" ot' rod Fl and the rod V liberated, and the machinestopped. The dies j', with the plates C and pasteboards D in them,=passunderneath a punch, G, which is attached to the slide Z. This punch, asthe slide Z descends, perforates the plate and pasteboard in each die.No stop mechanism is connected with thepunching device,none beingrequired, as the punch has a positive movement and cannot fail toperform its work. To insure an easy and smooth movement ot' the slide Zthe latter has a vertical rod attached to it, on which a spring, 0X, isplaced. (See l and 6.)

The next operation and the last is the inserting of the nails throughthe perforated plates and pasteboards in the dies j and the dischargingof the nails, with the plates and pasteboards upon them, from the wheelA.

H is a hopper, which is attached to a standard, I, on the platform F, inthe same manner as the other hoppers, J Z, but in a reverse position.

J is an inclined spout, which is underneath the hopper H, and inclinesdownward in a direction' toward the platform F, and has adischarge-spout, K, at its end.

Between the hopper H and the spout J Vthere are two parallel inclinedbars, p. y rlhese bars p p" are inclined in the same direction as thespout J, and they are provided at their upper ends, underneath thedischarge end of The parallel bars pfp 'convey the nails down to awheel, L, the bodies ot' the nails passing between the bars p, the headsof the nails resting on the upper lsurfaces thereof. The nails arelplaced in the hopperrHl in a promiscuous manner, and in case any shouldnot chance to pass properly between the bars p" p they are carried offby the spouts J K" and replaced again in hopper H. The wheel L has itspe riphery notched at suitable and equal distances apart, as shown at rin Fig. 7, and said wheel is partially encompassed by a iixed metallicstrap, s, which serves as a cover for said notches. The parallel bars p1o convey the Vnails down to the notches r in the wheel L",

depositing a nailvertically in each notch. The

wheel L" is placed loosely on a'vertical arbor, t", and it has aratchet, M, secured concentrically to its upper surface, wthwhich apawl, N, engages. This pawl N is.attaehed to a bent or right-angulararm, O", which is fitted bear againsta curved pendant, Q, by a spring, l

w",the upper end ofthe pendant Q, being connected bya pivot, y, to oneend of a lever, R, the opposite end of the latter being over the Y platee, as shown clearly iu Fig. 1.

The wheel L is made to rotate as follows:

Each'time the slide Z descends the harm" forces outward the har P", andthe latter by this movement actuates the arm O, so as to draw the pawl Nback over a tooth of the ratchet M, and as the slide Z and bar w risesthe spring forces the arm O and bar P" back, and the spiral spring o, inconnection with the spring so", causes the pawl Nll to'turn the wheel Lthe distance of one tooth of the ratchet M, which is equivalent to thelength of the spaces between the notches r" of the wheel.

By this means an empty notch,r",is presented to the bars p at eachmovement of the wheel L, the nails being carried around by said wheelbetween its periphery and the strap s to the point of their discharge,which is directly over the inner parts ot' two jaws, 31' y", the outerends of the latter working on pins u". lhese jaws have a tendency to bekept closed or toward each other by means of springs arranged in anyproper way, and they are separated or distended each time the slide Zdescends by means of a pendant-bar, z, attached to said slide. Thesejaws y y receive the nail S, Fig. l1, the wheel carrying the nailsbetween the jaws, and hold them directly over a die j', thelatter,as thewheel A rotates, being brought consecutively underneath the nails. Asthe jaws y y' are' forced apart by the bar a" the nail S, Fig. 11,between them is forced down through the pasteboard and plate in the diej' underneath by means of a rod, a* X, attached to the slide Z. Thus thenails are passed through the pasteboard and plate in each die,

upon them, are discharged from the wheel A as follows:

X is a bent lever, the outer end of which is connected, by a link, Y,with a lever or bar, Z, the lower end of thc latter resting upon a cam,A, on shaft Gr, the lever or bar Zl being kept in contact with the camby means of a spring, c'. The lever or bar Z is actuated by the cam A'"and spring c". and the lever or bar Zll actuates the lever X, so thatthe latter will throw the nails S, Fig. l1, from the wheel A' into aspout, B", which conveys them from the machine. (See Fig. ll.)

Thereisastop mechanism connected with the means employed for forcing thenails through the pasteboard and plates of the nails, and also y a stopmechanism connected with the means employed for discharging the nailsfrom the t ter 4will press down plate c and the catch X moved toliberate the rod V.

The stop mechanism of the means employed for discharging the nails fromthe wheel A is composed of a vertical rod, C", which passes through anarm,f", attached to arm y', and has a spring, g', bearing upon it andalso a lever, D', the spring bearing upon thelever and the lever bearingupon the rod U. The

inner end of the lever D is connectedby a i pivot to au 'upright rod,El, which passes through the plate e", the rod Ef having a collar, h,upon it above the plate c. ln case of anail failing to be dischargedfrom the wheel A', the rod Cf of course cannot be depressed the fulldownward movelnentof the slide Z, as the downward movement of C will bearrested by the nail iu the diej', and the rod Ef" will act upon plate eand the machine stopped, as before described in the other stopmechanlsms.
